  • Choosing the wrong filing status — especially Head of Household which has strict qualifying rules
  • Missing income sources like freelance work, side gigs, investment gains, or cryptocurrency transactions
  • Math errors on tax calculation or deduction amounts — double-check all figures
  • Forgetting to sign and date the form — unsigned returns cannot be processed
